Exclude prefix data validator not excluding pattern

Issue/Introduction

After adding the "Exclude Prefix" data validator to a data identifier, its still generating incidents from the expected exclusion.

Environment

Release : 16.0

Resolution

The Exclude Prefix data validator is an exact match string either prior to, or including the data touching the data identifier pattern.  If there are any characters at all (including whitespace characters) between the "exclude prefix" validator and the pattern, then there won't be any match. 

 

For example:

If you have a data Identifier matching the string "12345", with the "exclude prefix" "some_string" and your data set has the value "some_string 12345" then you will still get an incident.  This is because of the whitespace character between "12345" and "some_string".

Instead, you need to have the data Identifier pattern "12345" with the "exclude prefix" "some_string " (note the whitespace character)
